The "2" is for two-year old, the "T" is for toddler.
A child typically wears size 3T between the ages of 2 and 3 years old. This size is designed for toddlers who are transitioning out of the 2T size. However, individual growth rates can vary, so some children may wear 3T earlier or later than this age range.
It's pretty much semantics. 2T is a toddler size and only slightly larger than the baby size 24 months. Often the child can wear either.
The size chart is as follows: 3 months for 0-3 months of age 6 months for 3-6 months of age 9 months for 6-9 months of age 12 months for 9-12 months of age 18 months for 12-18 months of age 24 months for 18-24 months of age 2T for 24-36 months of age 3T for 36-48 months of age 4T for 48-60 months of age 5T for 60-72 months of age You will notice that at age four the median height ranges from 38 inches at the beginning to 42 inches at the end. The size chart for inches for 4T is 38-41 inches. Thus 4T is meant for 48-60 months of age not 36-48 months.
2T - 3T
The different places you go, the sizes change. For instance a five year old might have to get a size 7 in order to fit because of the store's sizing. For a 4 year old, generally it is toddler size 4,5, and some cases 6. Make sure it fits well! :)
The European equivalent of a toddler size 2T is typically around a size 92 or 98, depending on the specific brand and its sizing chart. In general, size 2T corresponds to a height of approximately 92-98 cm (36-38 inches) and is suitable for toddlers aged 2 to 3 years. However, it's always best to refer to individual brand size charts for the most accurate fit.
As the input size n increases, the function t(n) 2t(n/2) log n behaves in a logarithmic manner.
A 4 or if she was little a 2t and possible a 5 or 6
3r + 3r + 2t = 6r + 2t
2t-3-3 = 7 2t = 7+6 2t = 13 t = 6.5
Depending on the size (height, weight) and sex of the baby, you can either go with 2T or 3T. boys tend to be bigger, and 2T is usually for 1 and a half year olds, or small 2 year olds. 3T may be your best best.
19-2t = 7 -2t = 7-19 -2t = -12 t = 6
